      My computer does not turn on at all

      First, if possible, test another charger with your computer. If you are using a dock, please unplug it and connect the charger directly to your computer.

      You can also check if the charging indicator on the charger is on (white, green or blue light).

      After these checks, please let your computer charge for about one hour. Sometimes a computer's battery is completely empty and needs a long charge without use.

      If after all these steps your computer still does not turn on, you need to perform a hardware reset.

      Here's how to do it : 

      1. Turn off the computer.
      2. Unplug the AC adapter or power cable from the computer and remove the battery (for Dell laptops).
      3. Disconnect all peripherals such as USB drives, printers, webcams and memory cards (SD/xD).
      4. Press and hold the power button for 15-20 seconds to discharge any remaining power.
      5. Connect the AC adapter or power cable to the battery.
      6. Turn it on.
      If the problem persists, please contact Cleaq technical support.
